CULTIVATOR-TOOTH.

SPECIFICATION forming part of Letters Patent No. 258,263, dated May 23,1882.

Application filed February 14, 188 2. (ModeLl To all whom "it mayconcern:

Be it known that I, WM. D. STROUD, of Oshkosh, Winnebago county,Wisconsin, have invented certain Improvements in Cultivators orCultivator-Teeth, of which the following is a specification.

The nature of my invention relates to the use of a cultivator tooth orblade so attached to the shank as to be flexible 0r yielding when theblade strikes a stone or other obstruction.

It further relates to a device for changing and adjusting thelateralangle of the blade so as to throw the earth to the right or the left atwill.

It further relates to a combination of the two devices mentioned, whichtogether form a universaljoint, by which both thelongitudinal andlateral. position of the blade may be changed, all of which will be morereadily understood by reference to the drawings, in whic'hrup, D, andkey 0. The lower end of the spring engages a link, E, the other end ofwhich is engaged by the projecting end F of the wrist G on the blade,and it will be readily seen that the ,blade may assume the positionindicated by the dotted lines in Fig. 1, or any other intermediatebetween that and the full lines. The wrist G, to which the blade isattached, mayhave a dressed face or key-seat, as shown in Fig. 2, and agib, S, inserted and fastened in position by a key, L. By reversing theends of the gib S the blade will assume the position shown by the dottedlines in Fig. 2.

To fasten the blade laterally in a horizontal position a gib, S, may beused instead of S.

It is understood that I do not claim an elastic cultivator-tooth, assuch, but the devices by which the elasticity is attained.

I claim 1. The combination of the cultivator-tooth H, key-seated wristG, and gib S with the pivoted yoke K, substantially as shown anddescribed.

2. The cultivatortooth H, having a keyseated wrist, G, and gib S,incombination with the pivoted yoke K, link E, and spring B, substantiallyas and for the purpose shown and described.

XVILLIAM D. STRO UD.
